DRIVING-GEAR FOR MOTOR-VEHICLES.

Specification 01 Letters latent.

Application filed January 5, 1910. Serial No. 536,583.

Patented May 23, 1911.

To all whom it may concern:

Be it known that I, HARRY EDGAR LEVER, a subject of the King of Great Britain, and resident of J ohannesburg, Transvaal, have invented certain new and useful Improvements in Driving-Gear for Motor-Ve iicles, of which the following is a specification.

This invention relates to driving gear for motor cars and other similar motor vehicles.

It has for its object to so construct the driving mechanism that all the gears or wheels run in mesh continually.

The gear is operated on the ordinary gate rinciple, so that two gears cannot be brou t into action simultaneously.

I w' describe my invention in detail by aid of the accompanying drawings, wherein-- Figure 1 is a plan view of the driving gear. Fig. 2 is a section of Fig. 1 on line 10-41). Fig. 3 is an end elevation of the gear showing the several shafts in the positions in which they will usually be arranged relative to each other. Fi 4 is'a horizontal section of the gear; i 5 a section of Fig. 4 on line y-y; and ig. 6 an end elevation of Fig. 4. 1

In the construction of my improved driving gear I employ a main transmittin shaft 1 which is ada ted, at its outer en 2, to be coupled up with the engine or motor. On shaft 1 is keyed or otherwise suitably fixed a gear or toothed wheel 3. Axially alined with the main transmittin shaft 1 is a sec ondary transmitting shaft 4, one end of which, as shown, may be conveniently journaled in the end of said main transmitting shaft 1. On the inner end of the main transmitting shaft- 1 is fixed a gear or toothed wheel 5; and on the secondary transmittingshaft 4 is arranged a movableclutch member 6 which, on the side facing wheel 5, is constructed with an eccentric projection or boss 7 In the side of the wheel 5 opposite clutch member 6, is formed a corresponding eccentric recess 8-see Figs. 4 and 5-with which eccentric rojection or boss 7 is adapt ed to engage w en clutch member 6 is s id longitudinally of shaft 4 toward wheel 5. Clutch member 6 may be actuated to cause projection 7 to engage recess 8 by means of a clutch lever (not shown) or its equivalent.

9 in Fig. 4 is a feather key for clutch member 6; and 10 a collar provided on shaft 1 for preventing movement of wheel 5 longitudinally of said shaft. When eccentric projection or boss 7 is caused to engage cccentric recess 8 and wheel 5, then secondary transmitting shaft 4 is rotated directly from the main transmitting shaft 1.

11 is a toothed wheel or gear fixed on the outer end of secondary transmitting shaft 4.

12, 13, 14 are three other shafts which are arranged parallel with the main and secondary transmitting shafts 1, 4 respectively.

On shaft 12 is loosely mounted a toothed wheel or car 15 which meshes with gear or toothed w eel 3 on main transmitting shaft 1. Gear or toothed wheel 15 is constructed on the inside with a conical recess 16 which is eccentric to its shaft 12..

17 in Figs. 1 and 4 is a movable clutch member slidably mounted on a feather 18 in shaft 12. 19 is another gear or toothed wheel loosely mounted on shaft 12 at the other side of the movable clutch member 17. Wheel 19 meshes with the toothed wheel or gear 5. Clutch member 17 is constructed at each end with an eccentric conical boss or projection 20, 21 respectively; and wheel or ear-19, on the side facin the clutch memer 17, is constructed wit cess 22 correspondin to eccentric boss or projection 21. Clu-tc member 17 is adapted to be moved on feather key 18 by means of a clutch lover or its equivalent to clutch either of wheels 15, 19 to shaft 12. Eccentric boss or projection 20 engages eccentric recess 16 in wheel 15, when clutch member 17 is moved in one direction; and eccentric boss 21 engages eccentric recess 22 in wheel 19 when the clutch member 17 is moved in the opposite direction.

23 is a further toothed wheel or gear keyed or otherwise suitably fixed on the inner end of shaft 12, which toothed wheel 23 meshes with toothed wheel 11 fixed on secondary transmittmg shaft 4. y

24 is a toothed wheel or gear loosely mounted on shaft 13, which meshes with toothed wheel or gear 3 on main transmitting shaft 1. Toothed wheel 24 on the inside is constructed with an eccentric recess 25.

26 is a clutch member slidably mounted on feather key 27 in shaft 13. Clutch member 26 is constructed on the side next the gear or toothed wheel 24 with an eccentric projection or boss '28 which is adapted to enga e eccentric recess 25 in gearor toothed whee 24 toclutch the latter to the shaft 13.

an eccentric re- 29 is another toothed wheel or gear keyed or otherwise suitably fixed on the inner end of shaft 13. Toothed wheel or gear 29 meshes with a toothed wheel or gear 30. which is loosely mounted upon idler shaft 14. Toothed Wheel 30 on idler shaft 14 meshes with the toothed wheel 11 on secondary transmitting shaft 4.

31, 32 are thrust collars onvshaft 12 for gears or toothed wheels 15, 19, respectively; and 33 is a similar collar on shaft 13 for gear or toothed wheel 24.

The manner of operating the driving gear is as follows :'The first speed is obtained by clutching to shaft 12 gear 15, which meshes with gear 3 fixed on main transmitting shaft 1. The motion of shaft 1 is then transmitted to secondary transmitting shaft 4 through the gears 23, 11, on shafts 12 and 4 respectively. The second speed is obtained by clutching to shaft 12 gear 19, which meshes with gear 5 fixed on the end of main transmitting shaft 1. Shaft 12 is then driven from shaft 1 through gears 5, 19, and the motion is then transmitted from shaft 12 to the secondary transmitting shaft 4 through gears 23, 11. For the top speed or direct drive, the clutch 6 on secondary transmitting shaft 4 is operated to clutch shaft 4 to the gear 5 on the end of main transmitting shaft 1, thereby connecting the main transmitting shaft 1 direct to the secondary transmitting shaft 4. The reverse or backward movement is effected by sliding clutch 26 on shaft 13 into gear 24which meshes with gear 3 fixed to shaft 1. Shaft 13 is then driven from main transmitting shaft 1 throughgears 3 24. The motion of shaft 13 is then transmitted to secondary transmitting shaft 4 through gear 29 on said shaft 13, gear 30 on idler shaft 14 and gear 11 fixed on secondary transmitting shaft 4.
